Thank you for the various pointers. Ultimately, it was spare parts with compatibility mode switched OFF that solved it. The creation of the new resolution was not necessary for me either, although that did work also. FYI I was able to uninstall spare parts after compatibility mode had been disabled, and it still works. Thanks again.
